IN THIS STRUCTURE SINGLE CYSTEINES IN MUTS AND THE LN40 DOMAIN OF MUTL HAVE BEEN PLACED SUCH THAT CROSSLINKING OCCURS ONLY IN THE PRESENCE OF A DNA MISMATCH AND A NUCLEOTIDE (SEE WINKLER ET AL 2011, JBC). TO OBTAIN HOMOGENEOUS MATERIAL BOTH MUTS SUBUNITS HAVE BEEN CROSSLINKED TO A MUTL(LN40), WHEREAS FOR BIOLOGICAL FUNCTION ONLY ONE MUTL PER MUTS DIMER IS REQUIRED.
